The ball is probably wonderful, looks like great sturdy construction. I returned the ball because the directions stated to not use the ball for any other exercises than they show you. This was stated a number of times in all the literature. There are other exercised and stretches I use the ball for, so if they are that restrictive, I won't use it. If I had seen that first I would not have ordered. The staff at Dicks were very helpful in ordering this for me, and then returning. I did not blow up the ball at all. I did return the ball at Dicks and purchased the Fitness Gear (green 55cm) that was in store at Dicks, and I am extremely pleased with the Fitness Gear ball, it was easy to inflate even with just the hand pump - which is probably for safety - and I am very very pleased with my new purchase. It also cost less than the go fit and that is great! Hope this was helpful to someone out there. Don't be afraid of the hand pump, it's really not a big deal, and it's easy to use and store.
